TECHNICAL FIELD

The present disclosure relates to a technical field of support levelingof household appliances, and specifically relates to a support forhousehold appliance, and a household appliance.

BACKGROUND

Generally, leveling devices are arranged at bottoms of shells of thehousehold appliances, the household appliances can achieve a stableplaced state through regulating the leveling devices when the householdappliances are placed, and the leveling devices can support thehousehold appliances and keep the household appliances stable after thehousehold appliances are placed in a leveled manner.

Taking a washing machine for example, bolt supports are generallymounted at the bottom of a shell or whole set of the existing washingmachine, each bolt support comprises a lead screw, a nut gasket and arubber pad. The nut gaskets can be screwed up and down on the leadscrews, the lead screws can also be screwed up and down in screw holesof a bottom plate of the shell, and the height regulating of the washingmachine is achieved through lengths of the lead screws of the boltsupports screwed in the screw holes of the bottom plate; for a majorityof washing machines, heights are increased through counterclockwiserotation of the supports, the heights are reduced through clockwiserotation of the supports; and after the heights of the bolt supports areregulated, the nut gaskets for preventing loosening are screwed down tokeep steadiness.

For the supports of the washing machine, although the leveling of thewashing machine is achieved, users are required to carry out manualregulation, and user operation is extremely inconvenient if the deadweight of the washing machine is relatively heavy or a setting space isnarrow and small. In addition, during the long-term working of thewashing machine, vibration also acts on the leveling supports, thesupporting failure of the leveling supports is easily caused, and thus,the out-of-flat placement of the washing machine is caused.

For example, the existing 8 KG drum washing machine is generally about80 Kg and is relatively heavy, the regulation by customers is extremelyinconvenient, the condition that the washing machine is regulated to anoptimum state cannot be guaranteed even if the regulation is completed.During the washing, particularly spin-drying dewatering of accelerationto 1400 r/min from 0 r/min of the washing machine, great vibration willbe caused once the washing machine is not horizontal or suffers from afailure support problem, and thus, the comfort of use of the customersis greatly affected.

In addition, the vibration caused by the out-of-flat of the washingmachine may loosen screws of the supports, supporting brackets of thesupports may vertically move, a horizontal state of the washing machinemay be changed by the instability, and vibration that is more intensiveis caused. Due to the vicious cycle, the noise of the washing machinewill become louder and louder in long-time use, certain damage to thewashing machine is caused, and the service life of the washing machineis shortened.

Therefore, the leveling of the existing washing machines has theproblems of manual regulation, time and labor consuming and relativelypoor accuracy.

According to theembodiment, the liquid flow passage 107 inside the hydraulic plate 100is arranged at the embedding part, and the influence on the flowing ofthe hydraulic medium in the a liquid flow passage 107 caused by outsidepressure is avoided due to greater thickness of the embedding part, sothat by arranging the base parts 109 and the embedding part in a samelevel, the liquid flow passage 107 can horizontally extend to the liquidoutlet nozzles 101, and the stable circulation of the hydraulic mediumis ensured.
